Disable Noise Suppression on the HTC One

HTC promised superior phonecall sound quality on their flagship HTC One when they unveiled the dual-membrane microphones and the accompanying Sense Voice software. Consisting of a High SPL membrane and a High SNR membrane, the set up is supposed to rid of any unwelcome, outside sound interference in recording and calls by ‘assigning,’ different noise levels and sensitivities to their respective microphones.

With all this technology, it’s unfortunate that many HTC One users have suffered low quality sound including muffled and robotic-sounding voices during calls, rather than the promised better sound quality. This may be attributed to the fact that noise suppression kicks in when the device is at certain angles and positions, such as on your shoulder.

In order to combat the issue, XDA Senior Member grgsiocl has created a mod that essentially disables the noise suppression software. It has been tested to work with deodexed devices running 4.2.2 and 4.3. However, before you dive right in right away, it’s also recommended to take a look through the thread to see whether device variants or individual ROMs may be compatible or not. If the mod has had undesired consequences or you simply don’t notice any difference, grgsiocl has also provided a handy flashable zip file for Android 4.2.2 that reverts the effects.
